In this study, we discussed the inflammation and oxidative stress responses of rat lung caused by ozone and PM<jats:sub>2.5<\/jats:sub> versus that of rats exposed to saline, ozone, or single PM<jats:sub>2.5<\/jats:sub>. Wistar rats inhaled 0.8 ppm ozone or air for 4 h and then placed in air for 3 h following intratracheal instillation with 0, 0.2 (low dose), 0.8 (medium dose), 3.2 (high dose) mg\/rat PM<jats:sub>2.5<\/jats:sub> dissolved in sterile saline (0.25 mL\/rat), repeated twice per week for 3 weeks, the cumulative doses of PM<jats:sub>2.5<\/jats:sub> in animals were 1.2, 4.8, and 19.2 mg. Rats were sacrificed 24 h after the last (sixth) exposure. The collected bronchoalveolar lavage fluid (BALF) was analyzed for inflammatory cells and cytokines. Lung tissues were processed for light microscopic and transmission electron microscopic (TEM) examinations. Results showed that total cell number in BALF of PM<jats:sub>2.5<\/jats:sub>\u2010exposed groups were higher than control (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05). PM<jats:sub>2.5<\/jats:sub> instillation caused dose\u2010trend increase in tumor necrosis factor alpha (TNF\u2010\u03b1), interleukin\u20106, lactate dehydrogenase, and total protein of BALF. Exposure to ozone alone only caused TNF\u2010\u03b1 significant change in above\u2010mentioned indicators of lung injury. On the other hand, ozone could enhance PM<jats:sub>2.5<\/jats:sub>\u2010induced inflammatory changes and pathological characters in rat lungs. SOD and GSH\u2010Px activities in lung were reduced in PM<jats:sub>2.5<\/jats:sub>\u2010exposed rats with and without prior ozone exposure compared to control. To determine whether the PM<jats:sub>2.5<\/jats:sub> and ozone affect endothelium system, iNOS, eNOS, and ICAM\u20101 mRNA levels in lung were analyzed by real\u2010time PCR. These data demonstrated that inflammation and oxidative stress were involved in toxicology mechanisms of PM<jats:sub>2.5<\/jats:sub> in rat lung and ozone potentiated these effects induced by PM<jats:sub>2.5<\/jats:sub>. These results have implications for understanding the pulmonary effects induced by ozone and PM<jats:sub>2.5<\/jats:sub>. \u00a9 2013 Wiley Periodicals, Inc.
